These are for the wireless chips that come built in with various
Atheros/QCA SoCs. dts wise, the difference between pcie and the wmac is

AHB > PCIE > WIFI
AHB > WIFI

These will be used to replace the platform_device code with OF in the
following patch.

Drop the sentence. If we use auxiliary driver instead, should it
invalidate this commit msg?

I assume all these qr9xxx are capable of running Linux, thus you
document here other side - having them as part of other SoC.

But what about these? As well? Do they have other interfaces? IOW,
suffix "-wifi" is added ONLY if there is "qcom,qca9530" or
"qcom,qca9530-foo" somewhere or possible.

I assume you're referring to

They do. An example being the ar71xx driver which has

              - qca,ar9130-eth   # Atheros AR9130
              - qca,ar9330-eth   # Atheros AR9330
              - qca,ar9340-eth   # Atheros AR9340
              - qca,qca9530-eth  # Qualcomm Atheros QCA9530
              - qca,qca9550-eth  # Qualcomm Atheros QCA9550
              - qca,qca9560-eth  # Qualcomm Atheros QCA9560

I was advised earlier to change it to qcom instead of qca. Qualcomm
itself uses the qcom, prefix for its maintained drivers while the non
Qualcomm maintained stuff uses qca.
